Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 645, 117, 426, 660 i.e. 78584220 smallest integer divisible by all numbers.
Least common multiple (LCM) of 645, 117, 426, 660 is 78584220.
LCM(645, 117, 426, 660) = 78584220
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 645, 117, 426, 660 |
3 | 645, 117, 213, 330 |
5 | 215, 39, 71, 110 |
43, 39, 71, 22 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 43 x 39 x 71 x 22 = 78584220
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 645,117,426,660 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(645,117,426,660) = 3
common factors(in case of two or more numbers have common factors) = 90
GCF(645,117,426,660) x common factors =3 x 90 = 270
LCM(645,117,426,660) = ( 645 × 117 × 426 × 660 ) / 270
LCM(645,117,426,660) = 21217739400 / 270
LCM(645,117,426,660) = 78584220
∴ Least Common Multiple of 645,117,426,660 is 78584220
